In my review of Assassin’s Creed: Odyssey, I was blown away by the authenticity and level of detail in the game world. The game itself — well, it was fine. But the highlight was ancient Greece in all its classical splendor, and a new educational Discovery Tour mode aims to teach the history of that society through a gaming lens.

The free update, available now to anyone who owns the game, adds dozens of historical “tours” guided by a NPC, in which you can learn about the cities of ancient Greece, the life and crafts of the people who lived there, what they believed and how they were governed, and of course the many famous battles of the era.
